CCS/ADS114S08EVM: How to Program ADS114S08EVM EVM board using TI Code composer studio

Hi Ajay,

Welcome to the E2E forum! The ADS114S08EVM has the primary purpose of demonstrating the ADS114S08 device while displaying data and controlling the device using a PC GUI. It was not meant as a development platform. We cannot prevent you from using the EVM as you have mentioned, but we will not provide the firmware source code used on the EVM as some of the code is proprietary.

All that said, we initially debug our software using the JTAG connector (J2) using the Tiva 1294 Launchpad as you have stated. However, that was not meant for external code development as this will disrupt the ability of the GUI to continue operating with the EVM as intended. In other words, we are concerned that in the attempt to develop new code, the ability to further investigate using the current code would be lost. Our intention was to have customers develop code using the J3 connector instead.

If you add a jumper at JP1, you can place the onboard Tiva into a reset state blocking the level shifters (U5 and U7) from communication to the ADS114S08. At this point, you can connect any processor to the J3 connector and develop code. Also, when using the J3 connector you can use any desired pins from the controller and are not confined to the specific pins of the EVM. In the end, the number of pins to fly-wire are about the same and you do not need to disturb the onboard EVM firmware.

Best regards,

hi,

Thanks for sharing the information regarding this.

I would like to program the same microcontroller present in the EVM noard. Please tell me which Jtag i can use to program this EVM Borad.

Thanks.
